To all whom 'it may concern:

Be it known that I, RAYMOND DEQUEVIL- LEY, a subject of the King ofSpain, and a resident of Kiel Germany, have invented certain new anduseful Improvements in Submarine Boats, of which the following is aspecification. g. v

The present invention relates to submarine boats having double walls andthe object of the invention is to utilize the space between the outerand inner wall as a reservoir for liquid fuel and at the same time avoidthe: danger of the outer wall collapsing when the boat is submerged.v

The invention is shown by wa'y of example in the accompanying drawingwherein Figure l is a transverse -sectional view thereof; and, Fig. 2 isa part of a longitudinal vertical section through the boat.

The hull of the craft is encircled by the outer wall A and is of a shapethat insures stability and swiftness of the boat both when it floats onthe water level and when it is submerged. The inner wall B surrounds aspace of preferably circular cross section. The hollow space between thewalls A and B is designed for the reception of liquid fuel and isdivided into a plurality of compartments by means of the ,longitudinalframes C. The compartments communicate with oneanother through openingsc1 in the frames C.

On the top of the outer wall A a dome D is arranged, the interior ofwhich communicates with the .space between the walls A and B.- On thetop of` the inner wall is secured a partition wall E which extends inthe longitudinal direction of the boat and into the dome D. On the domeis arranged a feed pipe F which is bifurcated at its lower end in orderto provide for equal distribution of the fuel' to both sides of theboat. A screw cap f1 serves as a closure for the upper end of the feedpipe. On the dome D is further secured the housing of a cock G and asuction pipe H leads from said housing to the interior of the boat andcommunicates with a suitable suction and compression device (not'shownin the drawing) through the medium of which the fuel can be drawn outfrom the dome D and forced to the place of consumption. The cock G maybe o ened and closed by means of a rod G1 which leads tol the interior-of a dome J, communicating with the interior of the boat inclosed bythe wall B. In the interior of the dome Jis arranged a gage tube K whoseinlet pipes k1 open into the dome D and the space between the walls Aand. B. The partition wall E is cut out where the pipes k1 open into thedome and the space between the walls, so as to provide communication ofthe liquid to both sides of the partition wall. y

At the lowermost place of the boat, a valve M. is arranged in such amanner that by opening the valve the space between the walls A and B isplaced in communication with the water on the outside. The stem of thevalve M projects through the wall B and is provided with a hand wheelm1.

The above described arrangement is adapted only for use of liquid fuelswhich have a specific gravity less than the specific gravity of theWater and the other properties of which prevent a mixing or a chemicalcombination of the fuel with the water to an extent that makes the fuelunfit for use.

Let it be assumed that the valve M and the feed pipe F are openand thatthe craft floats on the water having the level m-. In this event thewater in the space between the walls A, B is in alinement with the levelw--fc` of the outside water. If liquid fuel of the aforesaid kind isintroduced into the space between the walls through the feed pipe F thefuel will be equally distributed on both sides of the partition wall Ethrough the bifurcated lower end of the feed pipe F. The fuel being ofless specific ravity remains on the to of the water an when the pressureof fue increases, the fuel forces the Water out through the valve M. Assoon as the outflow of fuel is rceived, the attendant closes the valve Mb; turmngthe hand wheel m1, completes the llling, and finally closes thefeed pipe F by means of the screw cap f1. If the valve M is subsequentlyopened, pressure of the outside water prevents the fuel from passin out.If the cock G is opened and fue is drawn off through the pi e H, thepressure of the outside water wi cause an equal amount of water to passin until the'space between the walls A, Bis almost filled with waterwhen nearly all of the fuel has been drawn oil". Through the gage tube Kit may be erceived from the'interior of the boat w en the fuel su ply ispretty nearly exhausted, and the coc G may then be closed in order toprevent water from passing into the fuel pipe H. Access of water to thespace be- I tween the walls maybe regulated by means of the valve Maccording to the degree of pressure of water on th outside.

The two walls A and B come togetherl at the uppermost place of the boat.

A submarine boat constructed in accordance with thepresent invention iscapable of carrying an immense amount of liquid fuel and the distance,which the boat can travel without renewal of the fuel supply, isconsequently considerably increased. Furthermore, the entire exteriorsurface of the fuel space is continuously exposed to the cooling actionof the water and the fuel is consequently highly cooled and insuredagainst danger of ire or explosion. Finally the space between the wallsof the boat being continuously in communication with the outside waterduring the .travel of the boat, the outer wall of the boat is entirelyfree of pressure and there is no danger of the outer wall collapsingeven at great depths.

The s ace between the walls A and B may be divi ed into separatecompartments by' means of transverse bulkheads, which compartments maybe emptied in succession and each of which communicates with 4the wateron the outside.

Having thus described the inventionthe following is what I claim as newtherein:

1. A submarine boat provided with a storage chamber comprising the hullof the boat as the inner wall of said chamber, and an outer shell spacedfrom the hull, as the outer wall of said chamber; said chamber lyingsubstantially below the plane through the uppermost wall portion of thehull of the boat whereby to give the least interference with the centerof stability and buoyancy of the vessel. l

2. A submarine boat provided with a storage chamber comprising thehull'of the boat as the inner wall of said chamber, and an outer'shellas the outer wall of said chamber, said outer shellbeing spaced from thesides and beneath the hull land having vthe top wall thereof lyingsubstantially beneath the horizontal plane through the uppermost wallportion of the hull whereby to so position i the storage chamber as willgivethe least interference with the center of stability and buoyancy ofthe vessel.

v3. A submarine boat provided with a liquid fuel chamber comprising thehull of the boat as the inner wall of said chamber, an outer shell asthe outer wall of said chamber, reinforcing means intermediate saidwalls, said outer shell being spaced from the sides of and beneath thelowermost wall portion of the hull, and having the top wall thereoflying substantially beneath the horizontal plane through -the`uppermostwall
